To all whom it may concern. dinal section through the improved device;

Beit known that I, WILLIAM R. MCGRATH, and,

a citizen of the United States of America, Figure 3 is a horizontal longitudinal secresiding at Atlanta, in the county of Fulton tion therethroug and State of Georgia, have invented certain Having more particular reference to the new and useful Improvements in Soap-Mix-. drawings, in connection with which like ing Devices; and I do hereby declare that characters of reference will designate correthe following is a full, clear, concise, and sponding parts throughout, the improved exact description of the invention, such as device may be stated to comprise a conduit- 10 will enable others skilled in the art to which like metal body indicated in its entirety by it appertains to make and use the same. the numeral 1, having inlet and outlet ways This invention relates to improvements in 2 and 3 formed in the longitudinally aligned soap mixing devices and has for an object and opposed ends thereof; the inlet portion to provide a soap mixing device especially 2 being internally screw-threaded as indi- 15 adapted for use in connection with hose cated at 4: for a purpose which will be subnozzles and the like, whereby that water sequently obvious.

as Figure 2 is an enlarged vertical longituis to be noted that the lengths of the opposed curved battles 9 and 10 are such as to permit of free passage or flow of water above the same, while the widths of such baiiies are less than the widths of the soap storage chamber adjacent the inlet and outlet ways 2 and 3. Hence, material interruption or deflection of the passage of the water flow into and from the device will be avoided and in consequence, proper How of water from the outlet way 3 will at all times be ensured. Furthermore, it is to be noted that the curved battle 9 extends upwardly, whereas the bafl'le 10 extends downwardly; although, if desired, this arrangement may be varied, such as conditions or preference may dictate.

By reason of the arrangement of the opposed curved bafiles 9 and 10 internally of the body 1, it will be understood that the :flow of water into and through the device will be diverted and that during such flow of water through the device, the same will come in positive contact with the mass of soap 8 in a manner sufiicient to permit of admixture of a proper quantity thereof with the water, whereby when it leaves the device by way of the outlet way 3, an efi'ectual cleansing solution will have been produced. However, because of the fact that direct stress of the water flow upon the soap 8 will be lessened by the interpositioning of the bathe 9 in the device, the soapy mass 8, together with wastage thereof by reason of excessive admixture of the same with the water flow will be obviated.

As a further means for ensuring proper positioning of the soap 8 in the chamber of the device 1 and likewise, to avoid excessive admixture of the same with the water flow, I may and preferably do provide the inner side of the screw-threaded closure cap 6 with a depending screw-threaded shank 13, arranging a nut or other suitable form of stop 14 upon the lower end thereof, while engaged about the upper portion of said shank is an expansible coiled spring 15, one end of which bears upon an adjacent portion of the closure cap 6, while the opposite endthereof has bearing upon a circular follower plate 16, which follower plate engages over the upper portion of the mass of soap 8 and with exertion of pressure thereon from the coiled spring 15, will cause said soap to remain in a compact mass and ensures proper positioning with respect to the water flow. The pressure of the follower plate 16 upon the mass of soap 8, it is to be understood, while being suflicient to retain the same in compact form, will not, in any way, detract from the efiiciency with which the device will, permit of the admixture of the soap with the water flow.

Also, by efiecting. vertical adjustment of the stop-1e upon the screw-threaded shank 13, it will be understood that vertical movethe breaking up of ment of the spring pressed "follower plate with relation to said shank 13 may be varied, as may be required.

In using the improved device, the screwthreaded inlet way 2 thereof is engaged with a suitable hose fitting arranged upon the hoze h, whereas a suitable form of nozzle n is engaged with the screw threaded end or nipple portion 17 of the body 1 of the device, in the manner indicated in the Figure 1. It is assumed in this connection, that a proper quantity of soap 8 has been placed within the soap storage chamber 0 the device and likewise, that proper adjustment of the spring pressed follower plate 16 has been eiiected in order that the latter will engage said soap and retain the same in a compact mass. With the admittance of water to the hose k, the same will pass through the inlet way 2 of the device and will continue thereon through upwardly over and by the sides of the upwardly curved baiiie '9, thus coming directly in contact with the soap mass 8 and causing a portion of the same to be admixed therewith. With continued flow of the water through the device, the same will pass the downwardly disposed curved baffle 10 and will leave the device by way of the outlet way 3, passing into the nozzle n from whence, it will be discharged onto the desired object. Because of the arrangement of the downwardly disposed curved bafiie 10, dislodgment of materially sized particles of the soapy mass 8 will be avoided and likewise, any tendency of the pressure of the water flow through the device to dislodge or effect wastage of the soap 8 will be avoided. Yet, however, admixture of a quantity otsoap sufiicient toproduce an effectual cleansing solution will be provided.

The supply of soap within the storage chamber of the body 1 or the device may of course be replenished aS required merely by removing the closure cap 6 and the shank 13 carrying the spring pressed follower plate 16 thereon. Also, as heretofore stated, by adjusting he vertical positioning of the sto nut 14: upon the screw threaded shank 13, the extent of movement of the spring pressed follower plate 16 with respect to the shank may be varied, as may be required.

Manifestly, the construction shown is ca pable of considerable modification and such modification as is within the scope of my claim, I consider within the spirit of my invention.

I claim:

A device of the character described comprising a body having inlet and outlet ways therein, a soap receiving and storage chamber within the intermediate portion of said body, oppositely disposed curved baffles fixedly mounted within the chamber adjacent the inlet and outlet ways and adja- 1,488,775 tit cent the opposite sides of said chamber, side of said closure, an adjustable stop ensaid baffies being of lengths and widths less gaged with said shank, and a spring pressed 1 than the internal area of said chamber and follower plate movably engaged with said inlet and outlet ways, the upper intermediate shank and adapted to have engagement with portion of the body having a, neck-like exthe soap within said chamber.
